// This code written per specifications found at

// Version 1.0
//
// This code calculates the Alpha, Delta, Beta and Gamma values
// but they are not used in the filter criteria as specified
// by the article which this code was based on.
//
// Look for additional changes as I tweak the below code.
// I will also include Scan feature and Backtesting in future release.

BLH=HHVBars(Close,25); // Tells us # of bars that have past since high reached. Used to determine lowest bar.
BH=LLV(Close,BLH); // Lowest close since the highest value was reached/
BBH=LLVBars(Close,BLH); // number of bars that have past since lowest value.
NBLH=BLH-BBH; // this is the number of bars in the formation of the left side handle. NBLH must be atleast 2 to be a valid handle formation.
// Now lets get the cup formation. Cup formation can occur anywhere from 23 to 145 days. The left side of the cup can be from 20-120 days and the right side can be anywhere from 3-25 days.
